Column types and type converters use TypeTags instead of Strings to announce their types. CassandraRDD#tableDef is public now. Added methods for getting keyspaces and tables by name from the Schema. Set version back to 1.0.0-SNAPSHOT.
Refactored Schema class - loading schema from Cassandra moved from the constructor to a factory method. This way, it is possible to add other ways of loading the Schema in the future.
Remove unused methods for returning system keyspaces from Schema.
